| 摘 要： | 铆接在航空等结构中的应用非常广泛,而疲劳损伤是影响其使用寿命的主要因素。在铆接件疲劳试验基础上,以有限元软件ANSYS Workbench为平台,分析了铆接件模型的应力状态,研究了铆钉排列位置、接触面摩擦系数、过盈量对构件应力场分布的影响,预测了疲劳裂纹可能萌生的位置;其研究结果为铆接件的抗疲劳设计提供参考。 |
| 关 键 词： | 铆接件 有限元 疲劳损伤 应力状态 |

| Abstract: | Riveting is extensively used in aviation structures. But fatigue damage induces a dramatic reduction of service life. Based on the fatigue test and the finite element software ANSYS Workbench,the stress state of the riveted model is calculated,the influence factors of stress distribution of the components,such as array location,friction coefficient,interference fit are analyzed and the probable position of the initation of fatigue crack is predicted in this paper. The results provide the theoretical basis for the design against the fatigue damage of the riveted joint. |
| Keywords: | riveted joint finite element fatigue damage stress state |
